The MAX9382/MAX9383 are high-performance PECL/ECL phase-frequency detectors with low propagation delay and high bandwidth, ideal for high-frequency clock synchronization applications.
The document describes the MAX9382 and MAX9383 as high-speed PECL/ECL phase-frequency detectors intended for use in high-bandwidth phase-locked loop (PLL) applications. These devices compare single-ended reference and VCO inputs to produce pulse streams on differential up and down outputs, providing a control voltage proportional to input phase or frequency difference.
| Supply Voltage Range (MAX9382) | 4.2V to 5.5V |
|---|---|
| Supply Voltage Range (MAX9383) | 4.75V to 5.5V |
| Typical Supply Current (MAX9382) | 44mA |
| ESD Protection (Human Body Model) | +2kV |
The devices feature a guaranteed minimum short pulse duration that completely eliminates minimum phase difference requirements during the lock condition.
Yes, the MAX9382 is pin compatible with Motorola's MCK12140, and the MAX9383 is pin compatible with the MCH12140.
The devices are available in industry-standard 8-pin SO and space-saving 8-pin UMAX packages.
